Almost never anything 'noticable', but it depends on the proximity of the star.
Only one star has any effect on Earth. The sun is the source of the heat and lightwithout which there would be no life on Earth. None of the other stars has any effect.

The sun and stars change positions because Earth moves
There is a change in frequency; this effect is called "Doppler effect".
The Earth spinning around.
Because from the star's viewpoint the Earth is insignficant and invisible.
All the planets (Greek for "wanderer") change position with respect to the stars. The reason is that they orbit the sun, as does the earth.
The earth is rotating around the sun. Therefore the position of other stars (although millions of light years away) are in different orientation to that of the earth.
Yes, because the Earth moves.(as well as the stars and the other bodies)
No. Weather patterns on earth, and the stars in space have absolutely no effect on each other of any kind.
It is used to compute the velocities of stars relative to earth by noting change in wavelength. It is also used to detect moving object like an aircraft by the reflection of radar waves.
